A Lurker's History of Paradox and the Paradox Community * by Stacy Rowley The Early Windows Days: the Software Understanding the context is very important in viewing what happened here, and the difficulties can not be underestimated.
To migrate Paradox for DOS (hereafter denoted PDOS) applications to Paradox for Windows (hereafter shortened to PW), the tables were forward compatible but everything else had to be redone. Oh, QBE still used the same logic. But to migrate applications and build new ones, the developer had to learn Windows while coming to grips with PW and its quite different approach. Even interactive Paradox had some learning, simply because of Windows and also because of PW. Folks had learned to develop PDOS 3.5 forms, then PDOS 4 dialog windows and forms, and now PW forms--all very different from the prior generation. One also had to learn how to develop PW reports. After all this, there was the event model. PDOS PAL was the language; PW ObjectPAL or OPAL, completely different from PAL, was the new and more extensive programming language. PDOS experts became PW neophytes; everyone was a PW neophyte. Next: The Early Windows Days: the People (the Community) Discussion of this article |
